Overview
The following information provides an example for configuring IPv6 DNS proxy to allow users to access a host through the DNS proxy. When the DNS server address is changed, you can change the configuration only on the DNS proxy instead of on each DNS client.
Prerequisites
The following information applies to Comware 7-based access controllers. Procedures and information in the examples might be slightly different depending on the software or hardware version of the H3C access controllers.
The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.
The following information is provided based on the assumption that you have basic knowledge of DNS proxy.
Example: Configuring IPv6 DNS proxy
Network configuration
As shown in Figure 1, the AC acts as the DNS proxy to relay DNS packets between wireless client and the DNS server. The wireless client accesses the host with domain name host.com through the DNS proxy.
Prerequisites
Configure static routes or a dynamic routing protocol on all devices to make sure the network connections are available.
Procedures
Configuring the DNS server
On the DNS server, configure the mapping between the host's domain name host.com and IPv6 address 3000::1/64. (Details not shown.)
Configuring the AC
1. Configure basic wireless features on the AC. (Details not shown.)
2. Specify the DNS server IPv6 address on the AC:
a. Click the System View tab at the bottom of the page.
b. From the navigation pane, select Network Configuration > Network Services > DHCP/DNS.
c. Click the IPv6 DNS tab.
d. Specify 4000::1 as the DNS server IPv6 address.
Figure 2 Specifying the DNS server IPv6 address
e. Click the Add icon 
.
3. Configure the AC as the DNS proxy:
a. On the IPv6 DNS tab, click the Advanced settings button 
.
b. Enable DNS proxy.
Figure 3 Enabling DNS proxy
Configuring the DNS client
On the DNS client, specify 2000::2 as the DNS server IPv6 address. (Details not shown.)
Verifying the configuration
# Execute the ping host.com command on the client and verify that the client can resolve domain name host.com into IP address 3000::1.
C:\Users\aa>ping ipv6 host.com
Ping6(56 data bytes) 2000::1 --> 3000::1
56 bytes from 3000::1: icmp_seq=0 ttl=128 time=0.671 ms
56 bytes from 3000::1: icmp_seq=1 ttl=128 time=0.571 ms
56 bytes from 3000::1: icmp_seq=2 ttl=128 time=0.373 ms
56 bytes from 3000::1: icmp_seq=3 ttl=128 time=0.538 ms
56 bytes from 3000::1: icmp_seq=4 ttl=128 time=0.750 ms
--- 3000::1 ping6 statistics ---
5 packet(s) transmitted, 5 packet(s) received, 0.0% packet loss
round-trip min/avg/max = 0.373/0.581/0.750 ms
